Hi Chris,

Glad to here you are getting something out of my long, hard struggle with the program  :o . OK 15 minutes  ;)

It will still need some tweeking but the basics are there, let me know when you get the thing ready to run and I will guide you through any mods.

OK got the toolchanger up and running and for the most part the macro is working just fine. Only one problem. is that when I change a tool I assume the macro changes the mode from absolute to incremental mode. where would I add a line to have the macro change the controler back to absolute coordinate mode once the tool change was complete. cause its playing crazy with my tool offsets.

only other thing I would change is to have the tool changer back up onto the paw a few more steps than what it is going past the paw. as it stands I have to set the steps to the paw slightly less than the actual distance to insure that it backs up till it makes contact. this creates a cumulative error if Im changing from say tool 1 to 6. but if I set it to exactly the right number it will go to the next paw. then go past a set number of steps and then back the same number of steps. this does not account for any lash in the drive so it does not back up snug onto the paw.

Hi Chris,

Here is the latest version with the mods you asked for, anything you altered in the original will need to be changed.

I have added the return to absolute mode and a variable to set the lock back to pawl distance.
